We need to figure out what percentage of 69 equates to 46. In other words, we need to figure out what percentage <u>times</u> 69 equals 46:
Now that we formed this equation, we can solve for the percentage as if it was x.
First lets simplfy:
Now we can solve for x just by getting x alone, which means we must remove the coefficent. We can do this by dividing both sides of the equation by 69:
=
Putting this into the form of percentage, we must multiply by 100. Since, the percentage form of a decimal is 100 times bigger(moved up 2 decimal places):
=
percentage = 66%

Answer:
A
Step-by-step explanation:
Given
p² + 2p - 8 = 0 ← in standard form
with a = 1, b = 2, c = - 8
Using the quadratic formula to solve for p
p = ( - 2 ± / 2
= ( - 2 ± / 2
= ( - 2 ± ) / 2
p = =
= - 4
p = =
= 2
